SHOE-NAIL.

SPECIFICATION forming part of Letters Patent No. 374,590, dated December13, 1887.

Application filed J unuary 2S, 1887. Serial No. 225,769. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK FLAD, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Shoe and other ClinchNails, which improvement is fully set forth in the followingspecification and accompanying drawings, in which the several figuresrepresent side elevations of shoe or other clinchnails embodying myinvention.

Similar letters of reference indicate corresponding parts'in the severalfigures.

My invention consists of a nail which may be readily clinched, as willbehereinafter fully set forth.

Referring to the drawings, A represents a nail embodying my invention,the same being formed of iron, brass, or other suitable material, havingin its shank or body near the point of the nail the depressions B, whichthin said blank at the places occupied by said depressions. It will beseen thatwhe'n the nail is driven into a shoe or other article and thepoint strikes the last or some other bed or anvil on which the articleis supported the point of the nail, which is substantially in an axialline with the shank, is deflected, thus causing the bending of the shankat the neck 0, the

latter being formed by the reduction of the shank due to thedepressions, it being seen that the depressions extend transversely orat an angle to the length ofgthe nail. The leather or other materialwill be surely clinched by the nail, and the latter will retain its holdin a firm and reliable manner.

In order to strengthen the neck 0, the faces of the same have ribs Dthereon, the same extending in the direction of the length of the shankand acting as a re-enforce without interfering with the bending andclinching action of the nail.

In manufacturing my nail I may take any ordinary wire-nail machine andprovide the pressing or clamping dies thereof and any separate partthereof with a projection or projecting part corresponding to thedepressions of the nail. When the dies hold the wire firmlyrin readinessfor the blow of the hammer, the aforesaid projection is adapted to acton the wire, so as to produce the depression or depressions B. I may,however, provide the cutters of themachines with such features that whenthe point of the nail is cut or produced the indentations or depressionsmay be simultaneously formed.

I am aware that it is not new to form a nail with a cut-away orrecessedportion for weakening the same, so that the nail when driveninto the leather or other'material and meeting resistance on theopposite side thereof may be bent so as to clinch or grip the material,and thus be firmly held in place, and such I do not broadly claim, but Iam not aware that the specific construction herein set forth, whereinthe recessed portion is on opposite sides of the nail and the lowerportion of the neck formed by said recesses is strengthened by ribs,asshown herein,has ever before been used.

Having thus described my invention, what I claim as new, and desire tosecure byLetters Patent, isv 1. A shoe nail formed of a single piece ofwire of uniform thickness, with its point in the axial line thereof andhaving on each of two of its opposite sides and near the said point asingle depression, substantially as and for the purpose set forth.

2. A shoe-nailhaving a neck near its point formed by recesses onopposite sides of the shank, said neck having the ribs D, substan.

tially as and for the purpose set forth.
